Hamabo Hibiscus is a perennial small tree or sizable shrub that originates from Asia and belongs to the marshmallow family. This plant features striking pale yellow blossoms that bloom from mid-spring until the first frost. Compared to other hibiscus varieties, such as Hibiscus rosa-sinensis, it exhibits greater cold tolerance and becomes drought-resistant once it is well-established. Regular pruning is recommended to encourage a bushy growth habit.
